What does os.path.diff("/home/", "/usr/") yield? "../usr/", I would presume? But that's obviously wrong:

IMO, the relpath method should just work textually on the pathnames. It's up to the user to ensure it makes sense to do so, e.g. by resolving symlinks beforehand if necessary.

The alternative would be for relpath to do this itself, but that would make it very unusual compared to the other path-munging functions, none of which touch the file system.
